motobecane ranger 7 variator

[moscam]

can anyone help me with the repair or replacement of a variator on a motobecane series 7 moped.either i need a new one ,which seems pretty unlikely, or possibly information on later model motobecanes which carry the same variator, or a supplier of parts for the existing variator, or information on any other variator that would fit.
the motobecane is a series 7 constructed 26/1/1976
